Feature...

At Install-time CMake is running in script mode and almost all vars you have in
the CMake-time context (within CMakeLists.txt) are not set.

If you want CMake-time var values available in your Install-time script
you'll have to either:

1) load some CMake-time generated file which contains the values

2) configure/generated your Install-time script itself

     configure_file(${CMAKE_CURRENT_SOURCE_DIR}/tInstall.txt.in
${CMAKE_CURRENT_BINARY_DIR}/tInstall.txt)
     install(SCRIPT ${CMAKE_CURRENT_BINARY_DIR}/tInstall.txt)
